SPECIFICATION forming part of Letters Patent N 0. 703,078, dated June 24, 1902.

Application filed March 8, 1902. Serial No. 97,230. (No model.)

To (all whom, it ntcty concern.-

Be it known that I, FREDERICK LEE Non- TON, a citizen of the United States, and a resident of the city and county of Racine, State of IVisconsin, have invented certain new and useful Improvements in Pneumatic Stackers, of which the following is a full, clear, and exact description.

The invention has for its object to provide an improved construction of chute or pipe for pneumatic stackers; and it consists in the novel features of construction hereinafter described, illustrated in the accompanying drawings, and more particularlypointed out in the claims at the end of this specification.

In pneumatic straw-stackers as now commonly constructed the straw chute or pipe whereby the straw is discharged from the blast-fan consists of two tube-sections telescopically sustained one within the other, so that by drawing out these sections the length of the pipe or chute may be varied as the construction of the stack progresses.

One serious objection to the employment of a pipe formed of telescopic sections is that any jamming or bending of one pipe-section must seriously interfere with the ease of movement of the sections in lengthening or shortening the pipe. By my present invention the tele scoping of the pipe-sections is avoided, and the lengthening or shortening of the pipe or chute is accomplished by varying the point at which the one section of the chute delivers the straw through the side wall of the other section.

My invention also provides a much lighterand more easily extensible construction of pipe or chute than is possible where the pipe or chute is formed of telescopic sections.

Figure 1 is a view in side elevation of a pneumatic stacker pipe or chute embodying my invention. Fig. 2 is a detail plan view of the outer end of the inner pipe-section. Fig. 3 is a detail side view of the inner and of the outer pipe-section. Fig. 4 is an enlarged view, in vertical longitudinal section, through the adjoining portions of the inner and outer sections of the pipe. Fig. 5 is a view in crosssection on line 5 5 of Fig. 4. Fig. 6 is a view in cross-section 011 line 6 6 of Fig. 4.

A designates the inner section, and B denotes the outer section, of the chute. shown, the inner section A of the chute is pivotally mounted upon pintles 2, that are sustained by a turn-table 3, that is revolubly supported upon the deck 4 of the threshing-machine, the turn-table 3 being shown as provided with an annular gear 5, whereby it will be shifted to effect the lateral swinging of the chute or pipe. The lower end of the chutesection Ais shown as enlarged, as at Ct, to set over the frusto-spherical upper end 6 of the bustle-pipe 7, the inner end of the chute-section A and the upper end of the bustle-pipe being thus united by a universal joint.

As shown more particularly in Fig. 4, the outer end of the chute-section A is open transversely, as at a, and at its top or longitudinally, as at a and this open end of the chutesection A is connected to the cut-awayinner end of the outer chute-section B. In the preferred form of the invention the chute-section B has the lower half of its wall at its inner end cut away, as at b, and the uncutaway inner portion b of the chute-section B extends over the open outer end of the chutesection A, as clearly shown in Figs. 1 and t of the drawings. Preferably the outer end of the chute-section A has its upper portion adjacent the opening a formed with straightened walls 61/3, and the lower edges of the portion I) of the chute-section B overlap the edges of these walls a and rest upon the narrow laterally-extendin g or offset portions a at the outer end of the chute-section A. (See Figs. 2 and 5.) A shield C extends outwardly from the end of the chute-section A, and in the preferred form of the invention this shield C is formed in piece with the outer end of the chute-section A. The purpose of the shield O is to close that part of the cut-away space I) of the outer chute-section that is not covered by the discharge end of the inner chutesection A when the outer chute-section has been shifted outwardly to lengthen the pipe or chute. The upper edges of the shield 0 lap the lower edges of the portion b of the chute-section 13. Preferably a guard-plate a extends upwardly from the opening a of the chute-section A into the portion 1) of the chute-section B and serves to prevent the escape of straw at the inner end of the chutesection B. From the construction of parts as thus far described it will be seen that when the chute-sections A and B are set together as shown the straw, under the action of the blast-fan, (not shown,) will pass in the direction of the large arrow, Fig. 4, from the chute-section A to the chute-section B, from which it will discharge onto the stack.

If the parts he assumed to be in the relative position shown in the drawings and it is desired. to lengthen the pipe or chute, the outer chute-section B will be shifted outwardly, so that the discharge of straw from the section A into the section B will occur through the side wall of the chute-section B at a point more remote from the outer end of the section B. hen the section B is thus moved outward, it is necessary that that portion of the cut-away space 5 of the section B that is notimmediately opposite the discharge end of the section A shall be closed or covered to prevent the escape of straw, and this closing of the cut-away space of the chute-section B will be effected by the shield C, that moves with the section A and is preferably formed in piece therewith. On the other hand, if it is desired to shorten the chute or pipe the outer chute-section B will be drawn inward, thus varying the point at which the straw is delivered by the chute-section A through the side wall of the chute-section B, and at such time the shield C, or a considerable portion of it, will overlap the body of the chute-section B.

In the preferred form of the invention the chute A is provided at its sides with rails D, fixed thereto and extending outwardly be yond the end of the chute-section A and beneath the chute-section B, and to the sides of the section B are connected the hangers E, carrying antifriction-rolls e, that set upon opposite sides of the rails D. This construction allows the chute-section B to be moved easily back and forth, so as to vary the point at which the section A shall deliver straw into the section B and to vary the length of the chute or pipe as an entirety. Moreover, by means of the rails D and hangers E the chute-sections are securely held together, the rails serving also to give rigidity to the chute or pipe. While any convenient means may be employed for elfecting the longitudinal movement of the chute-section B, Iprefer to use the simple means shown in the drawings that is to say, a rod 8 extends across the inner portion 1) of the chute-section B, and to this rod 8 is connected (see Fig. 4.) a rope or cable 9, that passes around a pulley 10, that is mounted upon a bracket 11, fixed to the top of the chute-section A. By drawing on either end of the rope or cable 9 the chutesection B may be moved inwardly or outwardly, so as to vary the length of the pipe or chute. As shown, the rope or cable 9 passes through an eye 9 of a standard G, and the ends of this rope or cable are fastened together. The standard G has its upper end extending to a point immediately above pintles 2 and above the center of oscillation of the turn-table 3, so that the relative position of the chute-sections A and B is not affected by the lateral swinging of the pipe or chute. Preferably the standard G is formed of sections hinged together, as at g, these hinged sections being formed with abutting shoulders 9 which limit the forward turning of the upper section of the standard G and, if desired, also the lower end of the standard G may be pivoted, as at y to a bracket 9 on the deck 4 of the machine. \Vhen the lower end of the bracket G is thus pivoted, it will be provided with a foot or extension 9 to limit the forward turning of the bracket G. The bracket G, being formed of hinged sections, can be conveniently turned out of the way and close to the deck, so as to permit the machine to more readily pass beneath bridges, through low doors, or the like.

The outer end of the chute-section B is shown as provided with the usual hood M, that is formed of segmental sections pivoted, as at m, and a cable N is connected to the outermost segmental section of the hood and passing through rings n,attached to each section, leads back to an eye 9 of the bracket G. Hence it will be seen that by drawing upon the cable or rope N the relative position of the sections of the hood M may be varied in manner well understood by those familiar with this class of devices. A chain m may be employed to connect the segmental sections of the hood M together-and to the outer end of the chute-section B and limit the downward drop of the hood.

Any convenient means may be employed for raising and lowering the chute or pipe as an entirety. As shown, the chute-section A is provided with a band P, that encirclesit adjacentitsinner end, and to the upper ends of this bandis pivotallyoonnected,as atp,arackharp, that is engaged by a pinion R on a shaft 0", that is journaled in a yoke S, that rises from the opposite sides of the turn-table 8. A rod .9 (furnished, if desired, with a friction-roll) supports the rack-bar p in engagement with the pinion R. A hand-wheel R upon one end of the shaft 0* serves as a convenient means for enabling the operator to turn the pinion in order to effect the raising or lowering of the chute or pipe.

It is obvious that the precise details of construction above set out may be varied by the skilled mechanic and that features of the invention maybe employed without its adoption as an entirety.
